This invention pertains to doors,and more erence characters are used to designate like particularly to auxiliary or track doorsv for parts-v use 'ont refrigerators or the like. Figure 1 is a front elevation of a portion Diiiiculty has' oftentimes been experienced of an iceboX embodying the device for pre- 5 in providing a means of egress and ingress venting leakage past the track or guideway 50 through an opening which when not in use associated therewith; i will be closed in such a manner as to prevent Figure 2 is a sectional plan taken substan leakage (of iiuid) past the closure. This is tially in the plane as indicated by the line particularly true4 with reference to iceboX 2-2 of Figure 1; 1n doors.' It is usual in iceboXes, particularly Figure 3 is a rear elevation of the device 55 those used in meat business, to provide tracks shown in Figure 1, showing the relation of the or Aguideways .into said iceboX providingy operating mechanism and the doors in closed means for holding the meaton a truck supposition; ported and slidab-le on the tracks, but here- Figure 4 is a sectional side elevation taken i: tofore difficulty has been particularly ensubstantially in the plane as indicated by the 60 counteredin preventing the leakage of the line 4--4 of Figure 3; refrigerating fluid past these tracks.

in place by fastening means 26 which may be of strap and screw construction.

The insulation 24 and 25 is suitably shaped to fit around the track 13, completely enclosing the same when the doors are in closed position,`and said insulation is also suitably shaped to lit around brackets or guides 2,7, provided on both doors, so that leakage is prevented' around` said brackets when the doors are in closed position. These brackets are preferably of arcuate shape""and1are`se cured to the doors by any means such as the bolts or screws 28 above thetrackand in'way of the path ofthe yoke 14. u

y Suitably'shaped links 29"and 3() arepivoted to the frame as at 31and 32 abovethe "doors'andeiitfend 'downwardly and are loosely f pivoted to the doors"throughslots-33 and 34 Aand any proper pin' connection. A bifurcatedv link is pivoted at 36' to afcrank 37 disposed `Vbetweenthe links 29and 30, said crank being rotatablewith a shaft 33 Vextending through the frame 19.A The link 35 is provided with 4arms 39aud 40 whiclrare pivotedlat 41`and 42 to floating links 43 and '44, said links being pivoted'at "45and 46 to links 29 and Y30, re-l spectively, intermediate their ends.

A contractile 'sprin`g`47 is provided'between ylinks 29" and 30'and secured thereto, tending of course to alwaysl urge-L doors 22"`and523 towards leach other tol closed position.. A crank-farm 43is non-rotatably secured tothe i"shaft '38',"saidc'rank being`= preferably urged upwardly; that is7 towards door closing' position, by means of a sping 49 secured as aty 50 A'to' the4 crank and as at l51 to they frame-19." A; flexible means 52 such as a' cable or cord of `any `material isf'secured tol'the crank 43 at *one endfthereof at53 and' said means-passes l' around a roller`54 pivoted to the bracket 55 and thence downand is secured to an adjustable connection 56y on the door 11. z

It will now be appreciated that whenthe door 11 is opened, due to a pull on theflexible connection 52, the crank 43 will bemoved in l a Vcounterclockwise direction. This of course will urge the'crank 37 upwardly, in turn'raising'links 35, 43 kand 44, thereby forcing links 29 and 30 away from each other,*eXpanding the'spring 47 and urging thedoorsf22and 23 to open; position, allowing passage'of the p yoke along the trackinto or out "'oftheicebox.

Should the door 11 then be closed, Vspring 49 will ofcourse urge the' crank 43 in a clockwise direction and'sp'ri'ng 47 will serve to draw'the links'29 `and 30towa`rdeacht other,

thereby' .closing the doors. Should the doors '-22'iahd`l23be in closed positionl and .should it be desired topass the yoke 14from one side to the other of said doors, and should the door 11 be in such position as to allow the passage Y of the yoke; that is, either fully opened or partially open without having operated the Y doors 22 and 23, it is only necessary to push the yoke against the arcuate lingers 27, forc-Y ing the lingers and consequently the -doors apartfwhich it will be understood, will allow the passage of the yoke, the spring closing the doors after passage of the yoke. Further, if in use itshould be found convenient, necessary or desirable to adjust the doors, i. e.,

to move the track 13 either to one side or the other, that maybe readily accomplished withouty changing the structurev of the Vdevice because due to the slots 33 and 34 provided in the' links and due to the pivotal and link connections between the crank 37 and the links 29e-nd 30, doors-22 Tand 23 may be pushed or lustration'andnotlimitation@ as variousand f' other forins'of vthe device williofcoursebe apparent to thoseY skilled'in theart without departure fromV thespirit of the inventioiior the scope ofthe claims.
